# Negative Dialectics Hegel's revolutionizing variant of dialectics where [[Negation]] precedes abstraction, which causes concretion -- where the dialectics (temporarily) stops -- to have the character of a *negation's negation*. Thereby the Hegelian subject -- with its fundamental, existential emptiness -- becomes an expression of what he calls *the night of the world,* which breaks radically with Enlightenment optimism. This Hegelian revolution preempts important ideas in Marx, Nietzsche, Freud and Heidegger.
